Stylized Motion Blur Houdini Digital Asset
Summary
This Houdini Digital Asset brings expressive, hand-drawn–inspired motion blur into 3D animation. Inspired by the SMEAR paper (SIGGRAPH 2024), it goes beyond realistic blur to give animators full creative control over how motion is stretched, exaggerated, and stylized.The HDA expands the effects to particles and Pyro solvers in Houdini.
Features
🎨 Art-directed smears – exaggerate motion per bone or across entire characters.
🌀 Ribbon-based offsets – generate flowing, cartoon-like smear trails.
⚡ Per-bone weighting – blend and layer smear effects with fine control.
🎭 Stylization controls – adjust the effects to your liking.
🧰 Production-ready HDA – works seamlessly inside Houdini’s rigging and animation pipeline.
Effects you can create
- Classic cartoonish stretched limbs smear.
- Exaggerated “speed lines”.
- Dynamic, playful distortions and trailing copies for fast actions.
- Dynamic smoke or dust trails from fast movements.
- Particle bursts and trailing effects that enhance motion arcs.
